PATCH 1/2 t5516-fetch-push: fix 'push with dry-run' test

In a while-at-it cleanup replacing a 'cd dir && <...> && cd ..' with a subshell, commit 28391a80a9 (receive-pack: allow deletion of corrupt refs, 2007-11-29) also moved the assignment of the $old_commit variable to that subshell. This variable, however, is used outside of that subshell as a parameter of check_push_result(), to check that a ref still points to the commit where it is supposed to. With the variable remaining unset outside the subshell check_push_result() doesn't perform that check at all.

Use 'git -C <dir> cmd...', so we don't need to change directory, and thus don't need the subshell either when setting $old_commit.

Furthermore, change check_push_result() to require at least three parameters (the repo, the oid, and at least one ref), so it will catch similar issues earlier should they ever arise.

PATCH 2/2 t5516-fetch-push: fix broken &&-chain

b2dc968e60 (t5516: refactor oddball tests, 2008-11-07) accidentaly broke the &&-chain in the test 'push does not update local refs on failure', but since it was in a subshell, chain-lint couldn't notice it.

Sigh/Blush. Thanks for finding an old screw-up.
